The differentiation of colors between the various forum ranks, and the possibility to lose the activity points (and obviously the ranks- if someone is banned).
1) Now that the forum is pretty big and sees a lot of visitors, posts and threads a day, a large number of the posts are spam or bumps etc.
Users often reply to a thread with +1, I agree, ditto and many other ways of announcing their agreement.
To avoid this, can we apply a like/invite system to each post? Say a person likes the post above him or a post somewhere in a thread, all the user needs to do is hit the arrow button which adds to the number of likes/dislikes that post has. That will be bound to cut quite a few posts out daily.
Mods can also implement a new rule that states those who don't use the system but rather post likes and such will be suspended. A reaper violation of the rule will lead to a banning...
2) With regards to bumps, threads are often bumped, especially by the OP (very often in the marketplace section). There are those users who delete their last bump post on their thread before reposting the bump, but what about having an automatic bump button?
Say a seller wants to bump his thread, every 24 hours he should have the option on his thread to 'bump' it. A designated button on the original post should bump the thread up automatically wothout having the need to post an actual bumping up post. That too should also cut back on the many useless posts the forum gets...
3) I like the idea of tagging users (read it on here before but including it anyway).
4) Quote and tag (3) notifications. - Should you be quoted or tagged in a post, instead of going back through pages ad pages in a large thread, simple notifications of the quoted or tagged post could redirect you directly to the specific post.
5) More organised PM inbox and outbox. I'm not exactly sure on the best way to do this, but my PM box for example is very cluttered. I have PMs from various users which come mid conversation with another member. Just a possibility, but perhaps all PMs can be sorted out under each user (kind of like a Skype chat style layout). I can click on a user in my inbox and see all the messages he/she sent me and my replies in a chat layout with dates above each message to show when each were sent).
What do you think?
Edit: Added some other ideas (they may have already been suggested).
I support the idead 2 & 3 and I think it will be really useful if them will be added in the new forum software (when this forum software will be released).
