Hi ,
i think it is very difficult to get this problem solved but i agree, there are to many AddOns of the same vehicle/weapon/unit. Especially for WW2. :'(
IMHO the order for AddOn making should be:
1. Search if that AddOn already exists, if yes maybe you can make a team with the maker
2. Are you really making something new (no, i do not need Rangers in the versions 1975, 1977, 1980, 1983, 1985, 1990, 1995 and 2003) at least not in different pbos.
3. Try to join a team for publishing a whole theme setting (AddOn(s), island, mission(s) ).
4. Look for correct tagging and versioning of your AddOn.
5. Make small but high quality AddOns. It is nice to have a F-15, F-16, F18 and F-22 in one pack, but if they behave/look like cr*p i do not want them.
6. Write a Readme including pictures and script commands, Weapon names and your contact adress.
7. Submitt it to a major site.
Only my opion
BTW How about some WW2/Nam style civis (maybe fat, or more sexy dressed) ?
