@0ZStarting off, I removed the post for you. Under the new updates you have a 10 min timer to hide your post, but if need be a mod can retrieve it for you.
Moving topics is a rare occurrence, so generally it's not in the user toolkit, however mods can move them with ease and even leave redirect links for those who wondered where the post went to. PM or mention one of us and we'd be glad to help.
BB Code information and ideas can be found here:
LinkWe may not have templates readily available but there are a few lying around and some good guides that may include a couple. HTML and CSS are generally avoided cause they can pose a possible security threat, especially if someone was to include any malicious content or coding.
Altering Usernames isn't quite the best option for us as it would affect the database and any linking content, such as PMs or mentions. Maybe in the future that can be a feature, but for the time being there's just not the ground workings for that kind of stuff.
As for the download part, I'm not too sure how many people would use that feature. You can talk to Mahz and see what he thinks in his
Dev Thread, but it's not a guarantee that he'll implement it.
All the best and hope that answers your questions.
