Be kind, stay on topic, and help the next person who searches for the same thing.

• One question per thread, in the board it belongs to. Mark the answer that solved it, so the next person finds it.
• Show your work. Attach the .dvk, or the smallest graph that shows the problem.
• No spam, no advertising, no abuse. Report a post you think breaks the rules rather than arguing in the thread.
• New members post a little slower and with fewer links for their first few days: that is how the forum keeps spam out, not a judgement.
• What you post stays. Threads and attachments keep their addresses for good, so others can link to them for years.

Moderators may edit, move, hide or remove posts, and silence or ban members who will not follow these rules. Everything they do is logged.
