most of your features requests can be made with the default configuration, some with a little help from a coder...
when the feature is not present, from what i see in your requests, they are present here in the database...
#12 ... hilarious... when you own a license, you can search in the phrases engine and replace the word vBulletin with whatever you wish... the only words you can't edit are the copyright in the footer of your forum... that's the only thing you can do regarding the name of the software...
oh, and relating each of your request with phpBB or IPB is cute... but we already have most of these features for years... ex:
- usergroup permission for guests to read, participate, download, etc...
- bots protection... a hack here is released to give "usergroup permissions" to bots, so you can give them a "no-permission" level on specific places...
- different colors for visited links, this is a well known feature of vBulletin... we have icons, CSS details and even eMail notification for new posts/threads in specific forums.
- ability to filter usernames, is very complete and efficient on vBulletin... like refusing to register users with hotmail.com emails, etc...
- size and colors of things over the forum are related to templates and CSS... everything is possible... this is not related to the software you use, but to the talent of your skin designer.
...
btw, from what i see from your request, i would suggest you post a very specific "Request Service" in the forum here:
