Tara, as a general rule we don't delete threads.
Forum Guidelines
Note: Staff will consider a request from the original poster to remove a thread/post they have made provided it was recently posted and not replied to. As a general rule, staff will not consider such requests once a thread or post has been visible for at least 4 hours or received 2 or more replies. In these cases, a request from the OP to lock the thread is more appropriate and will receive consideration.
Your welcome thread has been visible past the deadline and has plenty of replies. We can lock it for you if you want us to. You should consider the following though: You only get ONE thread in the Welcome & Introductions forum. If we lock it for you, you may not post any new ads until you get verified. My suggestion would be to clarify things by replying to the thread. Explain whatever misunderstanding you may have had with another member and get back to acknowledging those who are welcoming you to the site.
In the end, it is your decision whether to keep it going or to lock it. This is NOT the standard way that we do it. Normally it is up to us to decide whether to lock it or not. Given the fact that this is a welcome thread, I will let you decide on this thread if you want to lock it or keep it open.
