I'm really battling to style these command links - I think there needs to be more granularity with the CSS.
For exmple, on my Contact Us page, the Send button styles ok, but in another module the ModuleActions links have got inline styling which prevents you from doing the same thing. It's hard to explain without seeing it (if you create a league or group on PokerDIY you'll see the module actions are not styled the same)
Here is the HTML that is rendered in each case:
a href=' Webform_DoPostBackWithOptions(new Webform_PostBackOptions("dnn$ctr1207$Feedback$cmdSend", "", true, "Feedbackform", "", false, true))' class="CommandButton" id="dnn_ctr1207_Feedback_cmdSend">Send</a>
and
a id="dnn_ctr1661_LeagueEdit_cmdUpdate" class="CommandButton" style="border-style: none; display: inline-block;" href=" Webform_DoPostBackWithOptions(new Webform_PostBackOptions("dnn$ctr1661$LeagueEdit$cmdUpdate", "", true, "", "", false, true))">Update</a>
It's the bold bit that prevents you from achieving the same style in certain ModuleActions - it would be great if all inline styling were removed and the links were further categorised - ModuleActions, FileUploadCommand etc.
