plonis – I can offer you two popular alternatives:
1) Register a new screen name and (illegally) post asking for a welcome
2) Go into hiding for a week or so and then demand that you be given a welcome back.
In all fairness, and due to your personal experience, I believe it would be right for you to ask for your welcome in an entirely different thread than this one, and hijack it completely.
You don’t even have to choose between the options above – you could be like many other people here and choose both!
