This extension looks good. But the advertising on this pages implies that you can add a link for further event information. But it is not possible when using with Google calendars. You can add text with a link but no hyperlink (only back to google calendars), making the extension worthless for serious events people.
The relevant developer just tried the link functionality, both internally and externally, and it worked with the RokMiniEvents module. Therefore, we request that you post in the RokMiniEvents Forum to get your problem addressed, as it appears to be a specific, rather than general problem.
