Eru, don't take the blame for deletion; take the kudos for having created TWO practice boards instead!
If I may make a suggestion though; while the practice board is a useful tool for those who want to learn new skills, it is the INSTRUCTIONS that are the vital cog. So, if you're going to the trouble of writing out new instructions it would be prudent to keep a copy of them all somewhere safe, not just on the practice board which could be deleted again at some point due to lack of interest.
If the instructions were stored safely, say - here, in a purpose-built forum, or maybe just in some read-only threads in Michel Delving, they would always be safe and anyone could access them and even create their own, new phlubber practice board at any time. That way you wouldn't need to feel any sense of responsibility (not that you should anyway) for the maintenance of a practice board.
