For some time there has been a group on LinkedIn associated with the Forum (which I manage). It has a facility for posting messages, queries and answers etc. Quite a few people have posted opportunities and some have announced their availability for employment.
I suggest you use that Forum to offer jobs and/or your availability. Thanks.
The LinkedIn group can be found here: http://www.linkedin.com/groups?gid=690977
You need to register and join that group to read, post and respond.
