Ok a bit more details on these then...
1) "NEW!" - Some way of marking a thread so that it is readily apparent that it has a new post since the last time you have checked the thread.
&
2) "Goto Post" - A link on the forum level listing next to each thread that you have posted in that opens the page and takes you to your most recent post in that thread.
I think possibly the best thing to do for these two is to take your existing orange icon next to each thread and overlay an arrow on it (sort of like an arrow that is put over an icon for a desktop shortcut etc...) this way it indicates its going to be a shortcut and the orange still denotes new activity.
I don't think having the database manage these is going to be extremely crucial to be honest. Currently each letter someone types in a post is taking up 1 byte so 2 bytes here and there aren't going to make a huge difference. But I do think that some level culling the old entries is a good idea to prevent it from becoming extremely cumbersome, particularly with a growing user base.
3) Charts "View"-Window - The ability to set a time frame for hardware charts would be simply amazing...really no other way to say it. Just to be clear this would be specified as a date range for non-aligned graphs and a week range for aligned graphs.
If my concept of how the compare console graph works is correct then this should be fairly easy. The basic idea is to allow users to "zoom" in/out on an area and get more useful information. By allowing them to set a date range to look at for non-aligned graphs they can control the view window, and by allowing them to set a week range (ie week 6 to 40, week 1 to 15, etc...) for aligned graphs they can again control the view window.
This should allow the graphs to produce a lot more useful info than it already does by allowing people to look more closely at interesting trend periods more accurately.
4) Ignore List - I think this could help cut down on a lot of problems on these forums. I know there are some folks I would put on ignore and it would be nice =)
I'm not sure how you feel about this one, but there are a number of ways to implement it if you decide to go this route. You could either completely hide the post, or just not show any text in the box so the person would know that something was said but not necessarily what was said.
6) 5 second post delay to cut down on double posts
This one is pretty straightforward as far as design goes.
11) User specified posts per page - Allowing the user to set how many posts per page in their profile would be nice for some of the folks who maybe have more or less bandwidth/memory than normal. PS - I would still love a scaling width layout for the site...but I realize I am in the minority with my monitor of Doom =)
I think this one is general pretty easy to implement, were you for or against this one ioi?
14) Donating Member - For folks who donate cash to the site you should give them either a special title denoting their contribution or perhaps an avatar? Something to point out and highlight the folks who are helping out.
I think having one of our members who is gifted at the graphical banner making type stuff could make up something for this purpose.
15) Image Extraction - This one might be a bit harder but the basic idea is that you would allow people who are looking at a graph to download an image of that graph (or have it saved to the site itself) so they can link that graph in a thread rather than having 100 people come and look at the same graph over and over again.
I think this is one that should probably get shelved for a while since its a bit more of an extra than something new.
