I agree Mark & Sandee. It is unfortunate, and strange to me, that there is not more connection with tour members prior to a trip through these forums. As you said, useful for getting, and giving helpful tips and adds to the fun and anticipation with the learning of other's plans for their free time.
You did get replies that most tour participants do not know anbout these forums. I have seen that often said when this subject comes up. I find that odd, too. As often mentioned on the forums apparently most (many?) of tour participants are repeaters. And as somewhat independant minded travels I would have expected them to have heard of the RS forums as a source of information if not connection. Just a hunch on my part, of course as I have never run such a survey. And how could I if most of them are apparently not on these forums.
My experience (you can safely skip this as off topic to your post): I had a lot of technical problems creating my post looking to connect with those on pour tour (segway to hijacking your post to announce my tour: 21 day Best of Europe April 26. Send me a private message if you are on the tour and would like to discuss plans). As soon as I submited I realzied I had entered the wrong day in the thread's subject. But could not find the post. After several log out, clear chache, coookies and such I found it. I then got locked out trying to edit (you do not have permission). And then it dispapperaed again. Unlike one other boards I am used to, I could not see how to contact a moderator for help. I tested further creating a new post to see if I could duplicate the problem. It got worse as I created a post (new thread) and that one did get posted. But I was unable to edit or add to it to say, all is good and delete it. Well, I did put "tetsing please ignore" in the subject line but I did get a couple of replies and one that took me to task for not simply removing the post. (I wondered what part of "please ignore" was not clear). But as I was locked out of editing I could do nothing. After that kerfuflle apparently did get a mods attention as shortly after that test post, along with the less than helpful reply, it was removed and I was then able to at least post replies such as this. I have not tried to create another.
There is great information shared on these forums. It is a shame that they do not reach a wider audience of like minded travellers. MAYBE part of the reason RS does not promote that use of these forums is he does not want a larger audience reading these posts and thus making the venues even more popular from that wider audioence who do not participate in RS tours. That would not be a good thing. Just guessing out loud.
A couple years back I had looked at Road Scholar as mentioned in a previous post with the thought of taking one of their tours but the lack of participation in the tour specific boards that they helpful provide did concern me; "why is there no one here if this is a popular tour" sort of thinking.
It seems to me it would be easy, and beneficial to RS, and beneficial to tour members to simply include a mention of these forums in the trip resources or planning notes that every tour member receives. It takes some work and resources to provide individual boards for each tour as Road Scholar does but no need to start on that scale. Just a couple of lines in the usual boilerplate that is sent out.
Enjoy your tour Mark & Sandee; it should be wonderful.
