The main purpose of this was to help people find types of mods easier,The mod idea on the forum is essential too,with a search feature.Tags sound good and I think they can be implemented ingame too,right?Also,I think it's easier the way you suggested.How many tags,you think should possible.Also we are going to use excel ,write the mod then beside it the tags:then a small description,maybe a thumbnail for the forum,not sure yet.
