@Jonathan Greene,
Good points, though some deserve a bit more discussion.
#1 and #3 are probably the best, though #1 is often just being new to any forum, REI related or not. Perhaps a forum-specific "First Post" template pinned to the head of the forum topic list could help new folks see how to structure an appropriate first inquiry.
#2 just about defines a "newbie": someone with little or nothing to offer other than futures. I often see this interpreted as being asked to work for nothing. My response to that would be "no one gets a paycheck their first day on a new job, aside from a signing bonus", and those signing bonuses often have tenure requirements for the payout. Just to bolster one's own credibility, offer to accept a portion of the newbie's first deal profits as a show of good faith. While the relationship may ultimately prove untenable, that will be YOUR payment for the education toward becoming an effective mentor.
#4 and #5 really just show up shortfalls in the Bigger Pockets Forums.
#4 shows up the need for a more effective way to search the forums. BP's search function can be likened to Google in it's infancy. Yes, it searches, but there's no way to identify the "head" of thread where a question first appears. It also doesn't seem to recognize a quoted string versus the individual words in a search query. Perhaps an option to only search topic lines versus searching the entire forum database would prove helpful.
#5 is sort of the reverse of #4. There is no option link a question to multiple forums. I had the same issue with AOL decades ago - they called it spam, I called it covering all the bases. A single question could relevant to multiple forums, but attempting to engage the denizens of multiple forums is considered "spam" (it isn't). For example, in the left-hand column on this page, under "Financial, Tax and Legal" are forum topics which often overlap such as "Tax, SDIRAs and & Cost Segregation", "Goals, Business Plans and Entities" and "Personal Finance" could all be relevant to someone's question, but there's (currently) no way to engage the denizens of all those forums without posting in all of them (what you want to call "spamming").
