As you are getting alot of request what so different between 1.8 and 2.0 and most people who make mods do it for both versions
I don't think you realise the effort it would take to provide a version for what will effectively be a superseded version of the SMF forum software. The main challenge is around keeping two versions of data access functions, as SMF2 uses a completely different access mechanism. And the quiz uses a lot of database access due to its nature, it isn't simply making a few interface changes that can quickly be fitted to work with various SMF versions.
Ontop of that, many changes would require duplicate effort. It has taken me months to develop this mod, I do not have the time nor the appetite to spend a few more months getting it to work with the older version, then doubling effort required to make many alterations and additional functionality going forward.
Bear in mind this is something I am doing in my spare time. I have a full time job along with a family, so I can't dedicate all my time to it!
I am glad there is a lot of interest in the mod for previous versions and I understand the argument for people not wishing to move to SMF2 until there is a final release. I have SMF2 running on a site that has many thousands of visitors a day and it has been performing fine, but that isn't to suggest people that are uncomfortable with pre-release software should take the plunge. I am merely stating the fact that the software is stable enough for many people to be using it, so this is the version I am targetting. When you get to the stage where you are comfortable migrating to SMF2 you will have access to this mod too.
Thanks for your thoughts.
