No a bad idea - also maybe start a "Diary of a KiXtart noob" in the general topics forum, I always enjoy reading those

A guide from a starters perspective would be quite useful. By the time we think about writing an FAQ it's because we know most of the As to the Qs. This means that the documents can be dry and hard to read as we assume that the reader has a level of understanding which they may not.

The FAQ forum is moderated, so once you have something that you think is suitable, have a word with one of the forum moderators and get some advice on format.

Be prepared for your work to be criticised and debated - you are after all proposing to produce a document which is going to set out best practices for fellow starters, so it needs to be clear, accurate and uncontentious, and we can be quite vigorously opinionated around these type of subjects.

I hope I haven't put you off as it is worthwhile and you will find that your time and effort spent to give something back to the KiXtart community will be appreciated.
