If you wish to have your mod moved from this category to the modifications category prior to contacting a staff member to move the topic for you ask yourself the following questions to figure out if your mod is actually completed to Version 1:
-Does my mod have all the required vehicles for the mod to function as the original game play does?
-Does my mod have all the required personnel for the mod to function as the original game play does?
-Does my mod have all applicable lighting done for the vehicles to have them function correctly as the original game does?
-Does my mod have a "completed" map within it that not only permits all the original functions of the game to work, but is also "filled in" with the required content to be classified as a completed map?
-Does my mod have all the scripts within the version that I intend to release functioning as they are intended to work? Do they do what they are supposed to without causing critical failures?
-Does my mod function with regards to performance and stability in such a way that the game can be played without critical failures or defects?
If your modification can answer yes to the above questions, then it is probably safe to say that it is in fact a completed mod and it would be suitable to release it as a completed Version 1 modification and as such qualifies to be relocated to the modifications category.
Remember that you can have a stable release version of a modification while still developing the modification, you don't have to release mods with scripts/projects that are still in-progress and subsequently unstable or unreliable. The point of a modification is to evolve it, not to have an all-in-one release on day 1 that has every function within it, regardless to whether they work correctly or not. If something is not working as intended, perhaps it would be wiser to leave it out of the release version and add it at a later date once it is stable/functional. Most people who play the mods want a stable gaming experience, not a modification that has features that are unreliable or flat out do not work at all. Bear this in mind when making a release version of the mod, Beta releases are not quite the same as a completed proper mod since they may have issues within them that adversely effect stability of the game and should be noted as such.
If your modification does not meet the above criteria, it would be best to categorize it as an Alpha/Beta release and subsequently should remain in this category until it has met all the above criteria. Hopefully this topic makes it a bit easier to understand what denotes a release version vs. a beta trial version.
This topic may be edited over the next day or two to refine the information provided by other staff members.
