Please feel free to post problem surfaces.
Please feel free to solve and re-post solutions of problem surfaces.
Always scan files with anti virus software before opening a file from the Internet
(It's common sense i know but people forget)
you may create puzzles also but please mark them as puzzles so those that need surfaces for work can get priority...and put the solution in a separate layer on the puzzle file so people will know if they are right. you may want to leave your work lines on there so they can learn your method.
