I just received an email that the Call for Papers for the UKOUG Conference Series Technology & E-Business Suite 2010 has opened. The submission deadline is 2nd August, so you still have some time. The event itself is from 28th November to 1st Devember in Birmingham.
From my experience I can only say that this is the best European Oracle event around, so if you want to be part of it: Just do it! Submit your abstracts here: http://techandebs.ukoug.org/.
