In behalf of MATHalino, yes sir, we remember your posts and the posts from other members were lost too. A 3-month of updates was lost that time, the severely hit was the forum section. We cannot restore those posts anymore for technical reasons. Lessons learned the hard way. We are hoping for the best to come.
