I've approved your access now so you should be able to see the forums. We're currently about finished through season 30 of the main league, and the conferences; we will get you playing UKBBL games once these restart. These conferences are normally smaller competitions to help you build up experience of how the UKBBL operates (and SPP, of course!). One of the Conference admins will be in touch with you soon to either replace an outgoing conference team or to start a new division. Either way we'll hopefully be able to get you up and running once they restart in probably 3 weeks or so.
Have a mooch around the forums, and keep an eye out for a private message from one of the admins. We'll get you up and running asap!
Final thing every Monday we run a 90 minute UKBBL show on twitch with guest from around the league so if you have any questions don't be shy and drop in at http://www.twitch.tv/gcoleman76
