1. Hello and welcome back to MHB, Turgul!

We are happy to see that you have returned, and we look forward to your continued participation here!

On Behalf Of MHB's Staff,

Ackbach.
2. I recently linked to a topic here on MMF, a topic I titled "Probability Challenge" (which I generalized from a problem I found posted here) so I think that may be it, as I don't recall seeing any other linked topics here at MMF recently. Anyway, thanks for answering my question, I do appreciate it!
3. You are welcome! Saw your answers to the two unanswered threads Homotopy and Affine transformation proof. Thank you on behalf of the staff of MHB for the contributions!
4. If you don't mind me asking, how did you find us here? I'm just curious what avenues new members have taken to get here.
5. Hey, glad to see a familiar name show up here!

I want to welcome you to a great site and I look forward to reading your posts, as I know you to be a great contributor on MMF and I know you will be a great contributor here as well. I think you will enjoy this site, it has a lot to offer!

Best Regards,

Mark
