Hermes skin - Where is this button controlled?

Hello elbranscomb,
Added the code for theme-lib.start-conversation-button.

Make sure to add it to component section, then perform appropriate actions you need.

<#-- custom start conversation button -->
<#assign confirm="/search-before-post-mode/true?"/>
<#-- Check permissions for TKB -->
<#assign showButton = true />
<#if coreNode.nodeType == "board">
 <#assign qry = "SELECT conversation_style FROM nodes WHERE id = 'board:${coreNode.id}'" />
 <#assign nodes = liql(qry).data.items![] />
 <#if nodes?size gt 0>
   <#if nodes[0].conversation_style == "tkb" && !(coreNode.permissions.hasPermission("save_unpublished_article"))>
     <#assign showButton = false>
   </#if>
 </#if>
</#if>
<#if showButton>
 <#if coreNode.nodeType == "board" && page.name != "TkbPage">
     <#if settings.name.get("config.require_search_before_post") =="require_and_confirm" || settings.name.get("config.require_search_before_post") =="require">
         <#assign link = "/forums/postpage/board-id/${coreNode.id}"+confirm />
     <#else>
         <#assign link = "/forums/postpage/board-id/${coreNode.id}" />
     </#if>
 <#elseif page.name == "TkbPage">
   <#assign link = webuisupport.urls.page.name.TkbChooseTemplatePage.path("board-id",coreNode.id).build() />
 <#elseif coreNode.nodeType == "category">
     <#if settings.name.get("config.require_search_before_post") =="require_and_confirm" || settings.name.get("config.require_search_before_post") =="require">
         <#assign link = "/forums/postpage/category-id/${coreNode.id}"+confirm />
     <#else>
         <#assign link = "/forums/postpage/category-id/${coreNode.id}/choose-node/true" />
     </#if>
 <#else>
     <#assign link = "/forums/postpage/choose-node/true/interaction-style/forum/override-styles/true" />
 </#if>
 <#if user.anonymous>
     <div class="custom-start-conversation-button">
       <#if settings.name.get('board.enable_lazy_authentication') == "authenticateLater">
         <#assign href = link?ensure_starts_with(community.urls.tapestryPrefix) />
         <#assign buttonText = text.format("theme-lib.start-conversation-button.text") />
       <#else>
         <#assign href = webUi.getUserLoginPageUrl(http.request.url) />
         <#assign buttonText = text.format("theme-lib.start-conversation-button.join.text") />
       </#if>
         <a class="lia-button lia-button-primary" href="${href}">${buttonText}</a>
     </div>
 <#else>      
     <div class="custom-start-conversation-button">
       <#if !(coreNode.permissions.hasPermission("create_thread"))>
         <button class="lia-button lia-button-primary lia-link-disabled" aria-disabled="true">${text.format("theme-lib.start-conversation-button.text")}</button>
       <#else>
         <a class="lia-button lia-button-primary" href="${link?ensure_starts_with(community.urls.tapestryPrefix)}">${text.format("theme-lib.start-conversation-button.text")}</a>
       </#if>
     </div>
 </#if>
</#if>
<#--/custom start conversation button -->

To find it, look in the component "custom-hero-welcome"

Which shows it's actually in "theme-lib.start-conversation-button."

I don't have the conversation button code on hand, but you can request the code for these theme-lib.* components from Khoros.
