The forum offers absolutely no support... a waste of time.
Both tabs and sliders work just fine. If they didn't for you, I'd look for any CSS or JS conflicts caused by other extensions.
Despite it being a free extension, we certainly provide support but maybe we weren't able to do so in the middle of August. We did make sure to let our users know though with a huge 728x90 pixels banner at the top of the community forum...
If there is one thing that would make this even better, it would be the ability to apply image titles or captions.
What a joy! Hardly a day goes by that I don't silently thank the guys at Acyba for this product. It's made life 100 times easier while I can do 100 times more.
Apart from social media - which only addresses a particular audience- nothing grows & develops communities better than email newsletters. Well, that's if they're not spam and they are welcomed.
As far as support and REAL helpfulness, John at Acyba is in a league of his own.
A great product, which is being improved all the time, and terrific support must make Acymailing one of the top Joomla extensions.
I do in fact recommend it all the time to friends or developers looking for advice.
Using AWS, it's good to know that the load on my own server has been reduced and load times for users around the world will be much better. What does AWS cost? A couple of bucks a month.
The only drawback is an apparent increase in latency ("waiting for..." site) right at the beginning. Now if I could reduce that, the site would really fly! (I haven't even raised this with corePHP yet so they're bound to have something to say about it.)
corePHP's service is very, very good. They may not be as fast in response times as the best out there, but I've learnt that with a little patience, they always solve one's problems. Rafael, in particular, is a star!
So I can recommend this plugin with confidence - both on its own merits and the knowledge that corePHP is there to back it up.
(I've tried many extensions that promise mind-boggling speed improvements. Bar jomCDN, none of the others have worked on a complex site.)
