Having started to put links between articles in different language wikis, I wonder if it would be possible to create a process (a bot?) to occasionally search through all the interlanguage links to make sure that there is a reverse link back to the original wiki e.g.
If we have [[cy:Yr_Ariannin]] linking to [[en:Argentina]] [[es:Argentina]] [[pt:Argentina]] [[pl:Argentyna]] and so on, the process would check if there's a link in each of those wikis back to [[cy:Yr_Ariannin]] and if not, automatically create a link. I think it would help to tie the different wikis together into one overall Wikipedia.
Anyone think this is a reasonable idea, or how to do it?
