Additional information has been added to the presentation – EchoCharger and House Solenoid Replacement. This is in the description and expands on a key detail left out of the presentation. It would be too much work to redo the presentation to include this information, so it is in the description.

Regarding emails: There is no requirement to create a login and email account. The only function the login serves is to allow an email account to be added to the server database and then only for the purpose of automatic email announcements when a new posting is ready. Normally there will be no emails unless a new topic has been added to the site. I realize that some sites then use the emails to send out unsolicited and unrelated emails. Not so with this site. There is no mailing list maintained for any purpose other than to announce a change that might be of interest. If you have an invalid email then you will not get the announcement, which means that if it was purposely invalid then the account serves no purpose. Therefore I would suggest that if anyone wants to be notified and you are not being notified, you may want to correct the email address to receive the announcements. But again, this is not a requirement… just a heads up. Thank you.
