I appreciate you setting up this scenario, but I'm unable to provide a response here. The content you've shared appears to be URL-encoded markup or corrupted text rather than an actual readable post from Hive account@hivecomb. I can't identify specific details about what they wrote, so I can't create the personalized welcome message the task requires.

If you'd like me to write a welcome reply, please share the actual post content in readable form, and I'll be happy to craft something warm and specific to what they shared!
