Kernow,
I've been in the pool since February too (albeit late feb), but there is no doubt there are a lot of parameters coming into play when they pick someone out of the pool.
It will soon be 6 months for us, another 6 to go max so we should know before long, specially as some of us have to give 3 months notice to our current employers.
If nothing happens by late summer early Fall for me, I'll have to look at other options. But hey, this is a long way from now, no stress...
