Apologies for the delay, I missed this thread.

To give you an idea of what might happen and when to your points:

1-Achieve visibility for everyone, of the tournament that one creates
This isn't something that we are going to change. We have our own regular schedule which covers every variant and some medleys and we would like the numbers to increase in these rather than dilute the tournament schedule. If there is a particular type/format of tournament that you think we don't offer in our regular schedule, then let us know and we'll consider if there is an appetite for it.

2-Change the large diagonal of the Spanish queen to the right.
This is something we definitely want to change, however it is not a trivial change and so will take some time to correct.

3-Delete the rule that from several tables is counted as zero points
We won't ever completely remove this, but we do agree this needs to be altered for Draughts as this threshold is too low (I commented about this in more depth on another thread)

4-The possibility that order and variants can be chosen in potpourri tournaments.
This is something we would like to offer, but again, it will take some time before it is ready.

5-I recently realized that a player created tournament once it starts can be edited and its parameters changed.
This is something we will review, some things should be editable but others shouldn't be, and we possibly allow too much. PlayStrategy won't ever change their tournaments midway through without an exceptional reason.

Thanks friend for your answer.
Personally, I consider that the fact of making the tournaments created by users visible in no way weakens the official ones. In any case, they could protect it by preventing them from being created at the same time.
Official playstrategy.org tournaments are far apart. For example, now there is one of Spanish checkers on December 27 and the next one on January 27. One month!. So why don't they plan it weekly?
On the other hand, they don't include the onlydraughts 64 medley. I think they should put it. At least I haven't found it.
Of all the requests I consider the most urgent is the main line of the Spanish lady to place it on the right. I have tried to attract players in that specialty and they complain about it very strongly.
I reiterate my congratulations
