Cleaned this up a bit.
* Allow each member a personal, editable list of 20 active threads to watch
I believe this functionality exists already - you can see your active subscriptions via your control panel. Perhaps bookmark it?
* French forum
Sorry, diyAudio uses english as a first language. Second languages will be supported better in the future through <a href="http://babelfish.altavista.com">babelfish</a> integration.
* Elders choose their own title
Doesn't seem to be enough interest in this at the moment.
* Search link on main front page
Done.
* When searching to display your own postings, group results by thread, and within those, by time.
Too hard. Not enough votes.
* Allow pasting of large BMP images directly on Posts witthout having to do attachments
WYSIWYG editing is not vBulletin supported functionality. You shouldn't be posting BMP files anyway - it's an obsolete format. Kind of like running to the other side of town to speak to your friend, when you both have telephones. PNG, GIF, JPG provide great compression features.
* Removal of the 20 seconds elapsed time between searches
Sorry, this is a server load protection mechanism. Better you have site uptime than a spider takes it down for everyone
* Have a button to show all the threads started by a particular member.
This exists already. Under every post, there is a profile button. Click that then click "Show all posts by this user" in the top right.
* List of posts and threads started by people
This exists pretty much at:
http://www.diyaudio.com/forums/memberlist.php
Number of threads started? Hmm, if like everyone said they wanted that functionality I would do it but seeing as there haven't been 20 votes it is being put on the shelf.
