learnist has gone by the wayside.  At least I can't find it.  I have used several sites to purchase items online.

Still using various blog postings.  I had to use one for a writing class several years ago.
Learning platforms that I have used include" Coursera, Udemy, and GCFL.  I have practiced typing, used Lynda.com, Gale Online.

I have researched using several of the databases available at the public library and used email almost every day.

I have used Dabble, ProWriting Aid and Auto crit to edit and revise literary ramblings.  I am part of several Facebook groups.

Yes, things have disappeared. One of the sites used by Full Sail for experimentation is no longer being used.  They started that after I left.  That was almost 8 years ago.  I cannot believe how time flies.
