While bequeathing code to the community instead of having it buried with you is a very good thing it comes with a caveat. In most cases, it's not a good idea to pick up the result in its entirety - all of the code, the brand, the users, etc. That's baggage. It's a burden, not a help. In most cases it's better to make an explicit fork, or even just cherry-pick the best ideas and bits of code for use in a clearly separate project. If users think the new thing is better than the old, they'll migrate. If they don't, they won't feel entitled to come bugging you for support - or, if they do, you'll have a good reason to turn them away and concentrate on making the new thing great. Obviously you have to comply with the original licenses if you copy code, but you'd have to do that anyway. This way is likely to be far better for your own sanity and ultimately for users as well.
