The forum is slow because it was down for a long time due to a high volume of spam. Now that it's back up, people need to "rediscover" it.
As for your question, if you are not copying, reproducing, or distributing the map, then you would not be responsible to copyright violations (if any).
Note that some maps are not protected by copyright. Maps prepared by US employees or agencies are almost always public domain. Also, a simple outline of geographic or political boundaries, prepared from existing data sources, would generally not have sufficient originality to be protected by copyright.
