I hope that the old and the new users / club members will get used to the system that we had on our old A6S website and that we reinstalled - in a different layout - on this Wordpress site.
People use a broad range of social media these days, You can announce a table in the calendar with a description and post a link in whatever channel you like. Your opponent can book your table and then you have a confirmed opponent. Switching is easy and possible of course.
Or you can contact your regular opponent directly via any channel you like and confirm it in the calendar. However, try to use the calendar. Why?
1) you can attract a player outside your usual peer group, or try a ruleset / game you never tried before against a new opponent
2) we as your fellow club members need to know how many players to expect
3) click & go booking is easier and quicker than endless 'I don't know yet - I might come later' chatting. In our experience. First come, first go.
You can announce the table yourself, I regularly check the new tables and descriptions and will help you in case of questions.
