In reply to Otto42's last posts about the plugin not being usefull:
That may have been true when you posted, but now the plugin has reporting built in that shows you useful info like whether or not each ping service worked when pinged, in a nice and clear color coded way. Personally with so many services/urls not working any more, i find the plugin worth while just for this.
In regards to the registration:
I've already mentioned this before, but in short, i have no problem with it, there plugins are more than worth it (especially some of there other plugins) and if you don't want to stay subscribed you can just unsubscribe, it really isn't difficult :)
In fact I'd go as far to say that i'm glad they do it, because this helps them build their business and so they can spend more time making and supporting good quality plugins that i can use. They have to make a living and if their plugins don't make money for them, there's only so much free time they can spend on their support and development! A free plugin that also allows the publisher to make money is really the best of both worlds for a pluging user in my mind :) But well that's just the way my mind works :) :)
Also in regards to Spam:
For starters if you agree to someone's newsletter, than what they sand you is not Spam PERIOD.
Secondly, they don't send out all that many emails and quite often when they do it's about updates to there free plugins. Yes they do promote there paid plugins and sometimes other peoples software and services/products, but so far from what i've seen it's been good stuff if you're interested in that kind of stuff. But seriously you can just unsubscribe if you decide there emails don't have nay value to you, i personally haven't been sent anything from them yet that has made me want to unsubscribe, but that's just me.
Also in regards to the concern over them giving your email address to other people, i really don't think they'd do that, it just wouldn't be worth it for the bad name they'd eventually end up with because of it, their newsletter is worth money to them and their not going to do any thing to hurt that, plus i've seen no evidence of it since i've been subscribed.
Sorry for the long post, i never meant to write this much :)
Oh and sorry about the use of so many smileys, it's just my style lol
