I think that can loosely be translated to
Hello there, I wonder what may be happening around here
Thanks for the translation. Unfortunately I only speak and write English. (IE: I'm an old fart.)
Please translate for me and let Jht know how welcome he/she is here and that it's good to have another cyclist onboard.
Tell Jht that there's plenty 'happening around here' and we look forward to many more posts from him/her in the future.
