I'll hold out for a bit thenIn my personal opinion, it may be best to wait for the new timeline before getting involved. Usually I would encourage any new - or returning - members to jump in to get a feel for things, but the next timeline will bring fundamental changes to how the roleplay itself operates. So getting used to this system will be of little use to you by the time the next timeline rolls around.
Of course that's merely my opinion. If you have an existing character from this timeline still kicking around, you could jump in and shake off the cobwebs if you feel so inclined. Most people seem to be fully engaged in prepping and planning for the next timeline though (I know I am).
At any rate, welcome back!
