Charlie, we can try the call in web radio on thursdays. Its a very good idea. I wanted to a presentation also for meetup but i have been delaying it.
As for company option, this is something I decided to do ON MY OWN TIME/WEEKENDS etc so I guess they wont be interested. But I have you as a first contact if we ever need anything done. Infact, you had helped us on short gig 3 yrs back. Loved the solution. :-) I really appreciate your help and knowledge you share with us. <Ajas Mohammed /> http://ajashadi.blogspot.com We cannot become what we need to be, remaining what we are. No matter what, find a way. Because thats what winners do. You can't improve what you don't measure. Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.
