I plan in future (if I get enough digital sales to warrant it) to publish my comic in print either via lulu or another print on demand service. Is there a way to link the store link once I have it to my series/releases, so that people who browse it on GC would know they can buy it in print? If not, could that feature...

Linking a lulu/other print on demand listing to your comic?

Please recommend me review sites/youtube channels to send my work to in future once it's out
Basically I am looking for channels/sites that would be interested in covering/reviewing manga/manhwa-like fantasy isekai story (yeah, I know...) that was made outside Japan.
