In March of 2018, with the connect of MelonKing, OwlMan uploaded all of the past chat logs for NeoMail that had not yet been made public ever before. In this archive, he gives a quick run-down of some context of the post along with some other information to go along with the pages.
NeoMail - February Issue: MelonKing talks about how he is "working on a lil guide site that has some tutorials and useful links for web masters and new neocities users" - it would seem that this would turn out to be Daniel's Network.
NeoMail Summer #4 - Web 1.0 Awards?: A short time after this was made, WebJam was made.
[neocities mailings] you're cordially invited to the 'our space' webring: Post made pre-dating the rise of the our space webring.
NeoMail -- Neocities defaulting to https: On New Years day 2017, all Neocitie websites would be defaulting to SSL, this means that websites would no longer be HTTP but HTTPS. As a result of this, JeremyRedhead wrote a guide for people on what to do once their site was HTTPS. Published on the 8th of January 2017, the E-Mail is now mostly outdated by sometime.
In total this page has had 1 updates since it was uploaded.
