I can only answer detailed questions about online tools I use regularly (those listed above). *Those with an asterick are tools I often use for clients but don’t use myself. These means that as there are updates/changes I don’t always know about them right away. This means that in certain situations helping with these tools may take a bit longer than the others on the list.
There are hundreds of thousands of other online tools and there is no way I can answer detailed questions about all of them. But I can help you decide if a tool is trustworthy or the right one for your needs. I can also help you find the best support for a tool you are using and provide you with properly worded questions for that tech support.
