It is a false characterization to say versions later than 2.18 are 'incomprehensible'. The developers go to enormous lengths to make sure old code works, at the expense of some incompatible syntax changes, which are easily understood, and there is convert-ly to help you.
Others have made the vital point that list members, always willing to offer their expertise, and not likely to install or maintain an obsolete version to help you, so you are cutting yourself off from a very valuable source of assistance. Please consider installing 2.20 or the development versions, which are amongst the most stable open source that I know. Nobody is going to keelhaul you, but everybody will strongly urge you to follow the upgrade path. It's to your benefit. I for one will not answer questions for people running 2.18. The analogy would be insisting on running Windows 95 now, because you find WIndows 10 incomprehensible. Sadly, I do actually know people who want to do this. Andrew
