As of 18.03.01, this old theorectically obsolete Joomla site will become "more up to date," if still inminor ways. This I do, where I am JGW, the site founder and developer and PI for WLTres, because it is since end of 2016 possible to upgrade properly from a J1.5 site to the latest version, then 3.6, probably, to now: J3.8.5 at this writing. The links for the "upgrades-in-progress" versions of this site, one using Joomla 2.5, the other using Joomla 3.8.5, are listed on this site. If you are curious, take a look at one or both. Be prepared for "beta" site ugliness and/or incomplete content and/or incomplete navigation on both until either or both sites say they are ready to be "realease candidates" to, after some user testing, become the LIVE WebLearningTools Research site, you site visitor and I the beleagered site developer can then focus 99% of my tim on adding more up-to-date conent and weblinks to the latest LIVE site.
To keep site visitors to this site "more interested," I put a "Featured Weblinks" module in the right hand side column under "Latest Weblinks." For now "Feature Weblinks" has only the old "Interesting AI LearningProjects" category name listed. But there are 15 weblinks "of interest" to me as of several years ago, if that helps anyone!
In short: I may now, finally, have more time to devote to improving some content on this "old" but working wrll enough site while I also finish the upgrades to the "migrated" J2.5 and J3.85 sites so to the latter site I can finally add all the several years of web links I accumulated off-line to the new LIVE site. Yay......... i hope.
