Sorry I took so long to reply, my browser crashed, and this was one of 6 replies I lost :( Yeh this is a fair place to ask, but if you look in the link at the top: That's also the 3rd from the bottom in the results for a search for posts from Artesia conatining the word "button". The ones from the MBFM/MBSID hybrid are also mentioned in that thread, and there is a mention of pay_c having the original idea, and if you look for that, you'll also find my post about a good source for the tubing around the tacts. Now, I could go away and find these things and post them, or artesia could answer the questions, but the answers are already there, just a little search away :) It has occurred to me that it does help to use the search engine in a certain way... Maybe a wiki tutorial with pictures is in order?
