I'm trying to run the mojoPortal on Ubuntu (mono 2.6.7) and got a few bugs:

1. When I edit the properties of the module where the ColorSetting is used (eg Poll), then get an error:

System.ArgumentException: key
Parameter name: Duplicate key in add.

I corrected this by changing in mojoPortal.Web.mono/Controls/ColorSettings.ascx:

<span id="spnButton" runat="server" style="border: 1px solid black;padding: 1px 10px;cursor: hand;cursor: pointer;">&nbsp;</span>

to

<span id="spnButton" runat="server" style="border: 1px solid black;padding: 1px 10px;cursor: hand;">&nbsp;</span>

2. When I clicked on the link "View Messages" of ContactForm, then get an error:

Parser Error

Description: Error parsing a resource required to service this request. Review your source file and modify it to fix this error.

Parser Error Message: Cannot find type mojoPortal.Web.ContactUI.MessageListDialog

Source Error:

Line 1: <%@ Page Language="C#" AutoEventWireup="false" MasterPageFile="~/App_MasterPages/DialogMaster.Master"
Line 2:     CodeBehind="MessageListDialog.aspx.cs" Inherits="mojoPortal.Web.ContactUI.MessageListDialog" %>
Line 3:
Line 4: <asp:Content ContentPlaceHolderID="phHead" ID="HeadContent" runat="server">

Source File: /home/ykar/mojoPortal/Web/ContactForm/MessageListDialog.aspx  Lines: 1, 2

I corrected this by adding MessageListDialog.* to mojoPortal.Features.UI.mono (missed reference).
