The current forum software really isn't the best, and everything it can do now can be done with newer and IMO better software.

Let me quote Fizzer from the UV page so everything's clear:

|>An important feature of the WarLight forum is that it integrates with WarLight – i.e., it allows you to use the same login, link to your profile, etc.

|>The forum systems you mention won’t do this out of the box, and the open source ones are licensed under the GPL which prevents me from adding these features to them.

|>If you want a specific feature added to the forum, you can create an idea for that feature. If you find one that’s licensed under something more permissive like Apache or MIT then you can suggest that, but when I set out to add the forum to WarLight I could not locate any.

|>Switching to a GPL-licensed forum system is not possible, so I’m closing this idea.
