We are holding an informal seminar, currently most Fridays at 11am in the Maths Department at Leeds. There was a conference in the summer of 2011, from July 19th to 22nd. For more details see London Mathematical Society Northern Regional Meeting and workshop on Homogeneous Structures,

and there was a follow-up meeting in Prague, July 25th-27th 2012, http://kam.mff.cuni.cz/~hartman/WHS2012/
