Sorry I haven't replied sooner. I wanted to think about this for a bit.
I used the original Points MOD, and now the Cash MOD, but I haven't used/tried your's yet, so I'm not really sure I can answer this topic all too well.
However, that said, I have to suggestions, for both Napoleon and Xore:
(1) Perhaps we can create a global field, within the userstable, that can be used across the board, for this type of issue(??)
(2) Perhaps we can create a new table that stores users_id and a couple of global fields for all these different values that are needing to be stored. It would require a bit more JOIN sql statements, but it might resolve this.
Anyway, those are my two suggestions, at this point.... but than again, I do not really feel I'm in a good position to address the issue, as I really haven't tried to integrate Napoleon's and Xores MODs together.
Lastly, @Napoleon, I'd say you should just ditch the "points MOD".... I do not see it having a life here @phpBB much longer. Between the MOD Author no longer supporting it, and Xore's recent version of Cash MOD, I just do not see the Points MOD having a solid place, if any, @phpBB. That does not leave out your own MOD though. I would be interrested in hearing how it differs from the Cash MOD, and how the new issue of the CashMOD creating a new field within the users_table would affect your own MOD's. I think, from what I understand, it's going to be a major problem. You need a hard-coded table field name, which is just not possible with the Cash MOD, due to it's ability to have admin definable field names.
Anyway, I'll gladly look into the situation more, if both of you feel it's necessary for a third set of eyes and brain-cells.
