If you aren't playing then you could move from match to match and set up the tables/hands. You would need to have permission to set multiple matches, or use the IAC Id as generally people are only allowed to set one match, but that's easilly worked out. It's more complicated if you are playing and I'm not sure it's possible, maybe if you set your own match last it would work.
one thing to consider, too, with more than one match people will be ending at all sorts of different times, not normally an issue, but it is if you're waiting for everyone to finish so the review can start.
Starting out with two tables ( have to have two to have a match) would be wise simply because then we have to ask only 8 people to be patient while any glitches are dealt with, otherwise sure as taxes some will get restless, messages start flying about, all of which are distracting and have either to be ignored or if not, cause everything you are trying to fix revert to stage 1 etc. It's needlessly stressful.
I am still clutching onto the download version so can tell you the basics about setting up matches on the web version but not the more esoteric stuff like setting 3 or 4 matches simultaneously with preselected hands. Someone in the ACOL club can do this. or at least could on the download version, and sent me the program a couple of years ago but it's on a defunct computer. I wanted to do that for the team matches but they never got running smoothly enough at the start to feel any sort of hope that it would work very well. It depended on everyone doing what they are supposed to when they were supposed to do it and although some teams could be relied on, others were almost always in some sort of crisis at the start.
To do the other, have only one table would work and be easier but I honestly don't know how many members are keen to go through the hands like that. People are odd, they supposedly come to BBO to play but then park themselves in kib boxes and put down roots. I expect that if you set up such a table at any sort of regular time, there would likely soon be a regular group who showed up. That could then be expanded, perhaps?
As far as experts: some years ago now I organized play tables in IAC and had an expert come to be "on call" as it were for people who were having difficulties deciding what to do, a bid or a lead or a play, whatever.
People showed up to play, we usually had about 5 tables, BUT... NOBODY would ever ask for any help!! So the poor experts would be wandering from table to table, and eventually started just offering comments if they saw something they felt deserved comment. That came to halt when a member took fairly direct offense at having his bidding/play remarked upon, albeit nonjudgementally. So between that and the total lack of participation by the players, I cancelled the sessions.
I'd thought people would be keeping the expert running from table to table, not wandering like a lost soul wasting his time. At least one of the experts said at the time he'd be perfectly willing to return if we started that up again, but of course things may well be different now. To be honest don't now remember everyone who was doing that for us.
that's possibly not pertinent other than to demonstrate how totally unpredictable the members are. At least to me.
