I'm not sure if this has been addressed (can't find it via search) but are "looking for travel buddy" type questions appropriate here? Gut instinct is to take this kind of thing to the chat, but this is not visible or searchable and much less permanent. Thoughts?
The chat is searchable FYI (top right of the chat window).
However, we have suggested this post for finding other Travel.SE members.
However, as the Travel.SE site is a Q&A site for specific questions, polling for people to travel with probably isn't going to be on topic, unfortunately. Best bet is probably the linked thread, or the chat, and let us know where you'll be.
