Sorry, I don write in spanish, but I can read...
I have 2 remarks...
Firstly, Erel is much active in the forum, and respond to several tens of post a day, maybe even hundreds...
In my personal experience, I have found that sending a PM is much easier to get a "in time" response than using a "classic" e-mail.
During all day, EREL must find the time to respond to a fastly growing community and the dev of updates for our IDE's.
Second, surely you have not been the only one to have had issues setting up the remote builder access, so you could, instead of a well understandable complaint, you could have posted your issue and one of the several tens of B4i users would have tried to help you in the process, just as Descartex has done.
I have been a part of this community for over 10y, and have stayed away from b4i as it is to me, too much trouble form so little gain.
