I saw you removed a thread you added. Please do not do that. The purpose of these is to discuss or have answers to a question, and it can be useful for later, so don't remove these because "the topic is irrelevant". Same goes with message on walls by the way.
Hello there, I remember we already had a discussion about why this information wasn't valid and ask you to stop adding it. If there's something you didn't get, I'm available to answer to your questions. Thanks.
