How can I automate sharing event links?

About 6-8 times a week, I need to copy a url link and a bit of text from an event website page, add a short personal message and then post all of that to 5 different listservs.

Is there a software or web service which will make this manual process, which is about 25-30 clicks for each event, at least partially automated?

Are you able to identify the new link each week? Is there a date or sequence number or fixed location on the page, or is it a new page each week a predictable pattern in the url? Same for the text you want to copy, is it always after the link?

You can try automating the mouse clicks or just grabbing the page and pulling out what you want. An example or two would help.
